Indentation on a Patent Leather Shoe

I have a pair of red patent leather shoes that have been sitting in my closet. Apparently something was sitting on top of them because now there's an indention on the top of one of them. Is there any way to get this out? It's very small but noticeable to me. It looks like it might be from the heel of one of my other shoes.

Since most - if not all - patent leather shoes are actually plastic nowadays - you could try gently heating the spot with the dent and then trying to straighten it out by stuffing that part of the shoe with tissue paper or something similar.
